A Visualisation of 3D Lung Anatomy with Augmented Reality as Interactive Medical Learning

Abstract

Breathing is the process of breathing air or the movement of oxygenated (O2) external air into the body or lungs and exhaling air containing carbon dioxide (CO2) as residual oxidation out of the body. There are several organs that act as the respiratory system organs such as the nose, oesophagus, pharynx, larynx, trachea, bronchus, and lungs. Augmented reality can be utilized as a learning medium for the recognition of anatomy of the respiratory system organs presented in 3D with animation. In this research, to build the object to be used, researchers use blender software for object modelling process. To be able to display 3D objects, researchers apply target image techniques, namely by using a marker obtained from the book Sobotta Human Atlas Anatomy is adapted to the needs of preclinical medical students. When AR Camera captures the marker, the camera detects the pattern contained in the marker, and then matches the data stored in the database. When the pattern is found and there is conformity to that stored in the database, the application will display the 3D objects of the organ of the respiratory system with Augmented Reality technology. The optimal distance of marker detection is 15 - 35 cm, with a 30° - 90° inclination angles.
